Solvent-free, flexible, polyurethane injection resin with very low viscosity free, for sealing small scratches, work joints and expansion joints. Due to its low viscosity and extended gelation time, it is especially recommended for injection into injection hoses. K STER IN 4 does not cause corrosion of steel and iron.

The product is also available in a version with shorter gel time: 60 min.

Application

for insulating small scratches, expansion joints and work joints through injection hoses; for merging porous material in construction.
